I know all about getting beaten up by politically correct 20somethings. I was called a vile racist and worse by a mostly younger Twitter mob after writing a piece on 12.26.13 about dealing with an obviously unstable, intellectually-challenged black guy who wouldn’t shut up during a 4:30 pm showing of The Wolf of Wall Street at Leows 34th Street. The same fascist thug mentality (or something very similar to it) was behind a recent online petition to disinvite Bill Maher from giving a December commencement address at U.C. Berkeley. “Bill Maher is a blatant bigot and racist who has no respect for the values UC Berkeley students and administration stand for,” wrote Khwaja Ahmed, a member of the Middle Eastern, Muslim and South Asian Coalition, in a Change.org petition titled “Stop Bill Maher from speaking at UC Berkeley’s December graduation.” Berkeley chancellor Nicholas Dirks has blocked any chance of Maher’s invite being rescinded.
